Question

The disadvantage of impedance matching is that it ________

(a) Gives distorted output

(b) Gives low power output

(c) Requires a transformer

(d) None of the mentioned

This question was addressed to me in homework.

I want to ask this question from Class B Output Stage topic in chapter Differential and Multistage Amplifiers of Electronic Devices & Circuits

Answer 1

The correct answer is (a) Gives distorted output

The explanation: The disadvantage of impedance matching is that it gives distorted output. The Power amplifiers generally use transformer coupling because the transformer permits impedance matching.
